I think Excel is interesting in this regard. The common idiom in excel is to employ user triggered code generation by fill formula to adapt the ui to dynamically resized collections. Not exactly automatic, but is it sufficiently trivial to group with or trivial ui operations such as scroll or resize window that might also be needed to not interfere with the display of the dynamic collection?
